AbstractA study of indicator minerals in bedrock was carried out at the Mount Pleasant Sn-W-Mo-Bi-In deposit, in New Brunswick. This study was conducted as part of the Geological Survey of Canada’s (GSC) Targeted Geoscience Initiative 4 (TGI-4). It included mineralogical identification of polished thin sections and of heavy mineral concentrates produced from disaggregated bedrock samples. Indicator minerals identified in bedrock samples include the main ore minerals, cassiterite, molybdenite and sphalerite, as well as chalcopyrite, pyrite, galena, arsenopyrite, fluorite, and topaz. Although the deposit is well known for its wolframite content, it was not found in any of the rocks examined in this study. This absence is likely due to the small number of bedrock samples examined in this study.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This open file reports mineralogical data for bedrock samples collected from the Mount Pleasant tin deposit in west central New Brunswick. These data were collected as part of the Geological Survey of Canada's Targeted Geoscience Initiative 4 (TGI-4). These data will be used to identify useful indicator minerals of tin mineralization that could be recovered from surficial sediments.
